Kernel Panic on MacBook Pro 13" 2019

I have my MacBook Pro 13” 2019 (4 Thunderbolt port) model for nearly 2 years.

MacOS Big Sur 11.5.2


During the past few months, I’ve had my MBP randomly restarts with all fans spinning to the max.

it mostly happens when it’s not doing any heavy work. When I’m working or rendering videos, it’s fine.


When in low performance tasks like Safari browsing or just pausing VLC player, it happens. it happens quite frequently.


I’ve removed a lot of unnecessary apps, cleaned my cache, reset SMC and NVRAM.

Post the EtreCheck data, and post one of the panics, and maybe something stands out. Post those as attachments.

Remove all external devices, and see if the problem persists. Flaky USB hardware can cause crashes.

Run the Apple Diagnostics, and see if anything shows. Diags will show many hard faults, transient faults not so much.

If nothing shows from the above, next step is then probably Apple Support.
